A mutation alters amino acids in SecB of the general secretory pathway. Which proteins may no longer be able to interact within the pathway because of the SecB structural change? (Select all that apply) a) SecA b) ATPase c) SecY d) SecG e) SecE {Ans: a) SecA would no longer be able to interact within the pathway because of the SecB structural change (SecB ONLY associates with SecA)}Louis Pasteur's classic swan-necked flask experiment might not have disproved spontaneous generation if this microbial type was present: a) aerobic microbes b) anaerobic microbes c) endospore forming microbes d) viruses e) none of these would have impated the results {Ans: c) If *endospore forming microbes* were present, Louis Pasteur's classic swan-necked flask experiement might not have disproved spontaneous generation}Which of the following terms would best summarize the function of the general secretory path-way shown in Fig2.13?
